Figure 4 Characteristics of bleeding sites. The head region is the most commonly affected (n = 168/254), especially around the ears or earlobes (n = 46), forehead (n = 24), and nose (n = 23). The next most common site is in the upper limbs (n = 31/254), with the arms being the most common site of bleeding in this region (n = 14). Although most cases do not state the laterality of bleeding (n = 81), more cases are bilateral (n = 15), as compared to being unilateral bleeding (n = 10).
